I guess I'm just basing it off of what I've experienced and assumed she's experiencing the same. I've never heard those phrases meant constructively, even from what I would have called "friends", and it makes you feel really bad when you hear it. It's usually said with the implication that if you aren't having sex you must be miserable and depressed, and I've definitely heard these words quoted in the article:

“How can you go so long?” they ask. “I can’t imagine.”

As if you are doing something inhuman or so depressing to them that they don't want to think about it. Usually they even go as far as to say you aren't experiencing the whole of human existence.

"lower your standards" and such is also quite silly considering many women love being around me, and if I so desired I could easily go down that path with them I just don't want to. Sex is never "just sex", as people put it, with sex always comes waves and waves of drama that I just don't want to deal with, and being mentally ill I have plenty of drama in my head already without others adding to it.

I now only keep friends that don't ask those questions at all and mind their own business. Most of what I currently have as friends don't even really know for sure what sexual orientation I am and that's the way I like it.

Maybe her friends didn't mean it that way, but it's definitely received that way usually.
